Confined water pumping and irrigation integrated system and construction method for deep foundation pits in water-rich and iron-rich areas

Abstract

The invention discloses an integrated system of pressurized water pumping and irrigation for deep foundation pits in water-rich and iron-rich areas and a construction method. One side of the two telescopic rods is fixedly provided with two telescopic rods, one end of the two telescopic rods is fixedly provided with a support pad, and one side of the support pad is fixedly provided with a servo motor. The invention adopts the sealed depressurization well to extract the pressurized water within the scope of the foundation pit, and refills the mined pressurized water to the bearing outside the foundation pit through the integrated system of pumping and irrigation of the deep foundation pit in water-rich and iron-rich areas. In the pressurized aquifer, the invention not only reduces the impact on the surrounding environment, but also effectively avoids the frequency of operation failures such as pipeline blockage caused by the production of iron ion colloid, reduces the cleaning and maintenance costs of later operation, and greatly improves Work efficiency, at the same time has significant economic benefits and environmental protection effects.

Description

technical field [0001] The invention relates to the technical field of deep foundation pit confined water pumping and irrigation integration, in particular to a deep foundation pit confined water pumping and irrigation integration system in areas rich in water and iron. Background technique [0002] The traditional deep foundation pit pressurized water pumping and irrigation integration in water-rich and iron-rich areas is mainly used in the construction industry to extract and recharge the pressurized water in deep foundation pits in the construction industry. The excavation depth exceeds 5 meters (including 5 meters), or the depth does not exceed 5 meters, but the geological conditions and surrounding environment and underground pipelines are particularly complex projects; [0003] In the prior art, when designing and manufacturing the integrated system of confined water pumping and irrigation for deep foundation pits in water-rich and iron-rich areas, most designers will ...
